S.D.8-9 10. Describe the pathway of auditory nerve signals from the auditory nerve to primary auditory cortex. 1.- Auditory nerve – carries signals from the cochlea to the cochlear nucleus in the brainstem. 2.- Brainstem – signals are processed in the superior olive and inferior colliculus for localization and integration. 3.- Thalamus – the medial geniculate nucleus (MGN) relays signals to the cortex. 4.- Primary auditory cortex (A1) – located in the temporal lobe, it processes the basic features of sound (e.g. pitch, loudness) and organizes the tonotopically.

11. Describe both conductive and sensorineural hearing loss and why they occur. Can they be treated? Conductive hearing loss – cause (blockage or damage to the outer or middle ear (e.g. earwax, infections, or damage to the ossicles), and treatment – hearing aids, surgery, or medical interventions can restore sound conduction. sensorineural hearing loss – cause (damage to the cochlea (e.g. hair cells) or auditory nerve, often due to aging, noise exposure, or disease), and treatment (cannot be reversed, but hearing aids or cochlear implants can compensate for lost function).
